A welding structure of the underframe of the car head

Abstract

The invention discloses a vehicle head bottom frame welding structure. According to the vehicle head bottom frame welding structure, a bottom frame can be accurately clamped, accordingly, welding deformation is avoided, the welding size is ensured, and the bottom frame can be rapidly taken down after being welded. The vehicle head bottom frame welding structure comprises a base, a welding base plate and a welding frame. A seat support storing seat is arranged on the welding base plate, an in-out door capable of allowing the welding base plate to penetrate is arranged on the welding frame, a welding cavity for accommodating a vehicle head is arranged in the welding frame, and the in-out door communicates with the welding cavity. Guide rails used for sliding of the welding base plate are arranged on the base. A fixing sleeve and two supporting rods slidably arranged at the two ends of the fixing sleeve correspondingly are arranged on the welding base plate, and sliding structures are arranged on the supporting rods and comprise sliding blocks and sliding rails arranged on the base. Receding holes are formed in the welding base plate, the sliding blocks penetrate through the recedingholes, the sliding blocks are slidably arranged in the sliding rails, and the spacing between the two sliding rails is gradually increased from the ends, located outside the welding frame, of the guide rails to the other ends, located in the welding cavity, of the guide rails.

Description

technical field [0001] The invention relates to the field of vehicle processing, in particular to a welding structure of a front underframe. Background technique [0002] The front of the truck is mainly welded by multiple components such as the front gear, the rear gear, and the underframe. The underframe 1 includes a seat bracket 11 and two pedals 12. Because there is no connecting structure between the two pedals, it is easy to There are a series of quality problems such as welding deformation and dimensional deviation, and the welded bottom frame is difficult to remove from the welding mold, resulting in low welding accuracy and efficiency of the bottom frame. [0003] China Patent Authorization Announcement No. CN 104668801 B, the date of the authorized announcement is 2017.01.04, the name is "a welding line for the base of checkered plate logistics vehicle", which discloses a welder including a conveyor belt, a panel conveying station, and a wheel fixing inner plate. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages in the prior art that welding deformation and size deviation between the two pedals are easy to occur when the underframe is welded, and that the underframe is difficult to remove from the welding mold after welding and forming, and to provide a Carry out accurate clamping to avoid welding deformation, ensure welding size and quickly remove the welding structure of the head chassis after welding
